ABS light, Service 4x4, Service Parking Assist, and Traction Control PROBLEM SOLVED

[OggyOggy]

There is a different thread where I asked for help troubleshooting this sudden problem where all four warning appeared simultaneously. A number of people here offered ideas but I found someone with an almost identical problem on YouTube.

Nutshell: All 4 errors were caused by a bad ABS brake sensor. In my case the passenger side rear. I replaced the sensor ($22 Autozone) and all four errors were gone.

I hope this helps someone in the future from wasting money on troubleshooting.

Kindest regards folks,

I'm curious as to how you determined that it was the ABS sensor?

Acually I didn't. I found a video on YouTube of a guy with a 1500, same year as my 2500 with exactly the same problem. Since the only place I had been working was near the passenger side rear tire I replaced that sensor and fixed the problem.

You got lucky finding that, cuz it could have been many things that caused that.
My old 2002 Ferd Excursion had a cracked coil (not visible), and it caused all kinds of problems with almost every sensor on the vehicle. It was shooting out stray RF through out the vehicle. Replaced that coil, and it solved it.

Five minutes with a scan tool would have answered the OPs initial question. Right down to which wheel.
